The .parse_request() ethnl operation extracts the relevant attributes
from the netlink request to populate the private req_info.

By passing genl_info as a parameter to this callback, we can use
the GENL_REQ_ATTR_CHECK() macro to check for missing mandatory
parameters.

This macro has the advantage of returning a better error explanation
through the netlink_ext_ack struct.

Convert the eeprom ethnl code to this macro, as it's the only command
yet that has mandatory request parameters.
